Linear Motors & Absolute Encoders

Eagle Lasers Linear Motors & Absolute Encoders

Where Speed Meets Accuracy

Precision starts with motion. Eagle’s linear motors deliver direct-drive accuracy, zero backlash, and the dynamic control required for high-speed fiber laser cutting.

Absolute Linear Encoders

Speed without precision is just motion

Eagle builds both into the machine from the ground up: linear motors on all axes for direct, contactless drive, and absolute linear encoders for real-time position feedback. Unlike rotary servos with gearboxes and belts, our linear architecture removes conversion losses and mechanical play—so the cutting head goes exactly where the program says, every millisecond.

  • Eagle-manufactured linear motors on X/Y/Z axes
  • Absolute optical encoders (Renishaw “RESOLUTE”) with continuous, closed-loop feedback — up to 1-nanometer measurement resolution and 22 kHz update frequency
  • Ready to cut in ~15 seconds after power-on — no homing routine required

Advantages of Linear Motors Over Servo Mechanics

  • No friction, no backlash: The mover glides over the stator without contact. No screws, belts, or gear lash to fight against.
  • No conversion losses: Drive force is linear from the start — no rotary-to-linear conversion, no “sweet spot.”
  • High acceleration & dynamic accuracy: Hit peak acceleration/deceleration and maintain toolpath fidelity even at top speeds and power levels.
  • 24/7 reliability: With virtually no wear points, the motion system stays consistent for years.
  • Minimal maintenance: Fewer consumables, fewer adjustments, less downtime.

Result: Higher real-world throughput (not just headline speeds), cleaner edges, tighter tolerances, and consistent part quality from the first part to the last.

Speed without precision is just motion

We don’t add linear technology to a conventional frame; we engineer the entire machine around it—structure, geometry, controls, and serviceability. That’s how we achieve the rare combination of speed, stability, and longevity that keeps your cost-per-part low today—and still low ten years from now.

What it means on your floor?

  • Less friction → less maintenance: No screws or belts to tension or replace, no lubrication points along long axes, fewer service stops. Contactless and wear-free sensing—no degradation over time.
  • Higher results per shift: True-to-program toolpaths at speed mean more good parts per hour and fewer slow-downs for quality rework. Full control of dynamic motion—the controller corrects in real time as the head accelerates, corners, and stops.
  • Accuracy that lasts: The same performance after years of operation—not just on day one. No homing after power-on—machine “knows” its position immediately.
  • Confidence at high power: When wattage climbs, motion stability matters more. Linear and absolute feedback keeps cut quality steady at the top end.
